y In the. selected embodiment of the invention herein disclosed, thereis illustrated in Figure l a, portion of a floor finishing machine 2having carrying wheels 3 and provided with a suitable motor} andapolishing roll or drum 5. The drum is detachably secured to a shaft 6by suitable means, not shown and the shaft is driven mm the motor 4 bysuch means as a belt drive I 1, indicated n Figure 2'.

,The, periphery ofrthe polishing drum. or roll 5 maybe in the form ofbristles. fabric. steel wool, or any other suitable material capable ofproducing the desired results when a polishing medi- ,um suchas wax isappliedtothe periphery thereof. The drum 5, is shown mounted within a,suitable-hood 8 secured to the machine frame and detachable relativethereto to providelac- Jcess to the polishing drum 5 and its associatedparts. s a V 7 An important feature of ,--the presentinvention..resides,inthe method of applying a suit able polishing wax toa surface to be polished, whereby the application of the wax to saidsurface may be accurately controlled under all working, conditions, To.thus accurately control 7 the application ofthewax to the surface,thewax is.molded or otherwise compressed into a solid .mass or body9,.adaptedto be received in a suitable holder positioned adjacent totheperiphery of the polishing drum 5 in such amanner as to support thewax-bar infrictional contact with ,theperiphery of the drum. I

'To thussupport the wax bar 9, there is shown in the drawings a holder II which may be pivoted toawall of the hood 8 by suitable pivots I2 shownV 5,isian enlarged detail sectional view on the line 55 of Figure 1,; I

in Figures 1 and 3, The form of holder herein shown is provided withdownwardly and inwardly turned opposed flanges I3 and I4 between whichthe upper enlarged portion or backing I5 of the Wax bar 9 is received;The backing l5 of the wax bar 9 is shown having a longitudinallyextending tongue I6 which serves to rigidly anchor the wax bar to thebacking portion I5, as will be understood by reference to Figure 7. Thebacking l5 may be made of wood or any other material applicable for thepurpose.

'The holder I I is thus swingable in a vertical plane whereby the lowerface I! of the wax bar 7 9may be swung into or out of frictional engage-,ment with thperiphery of the drum 5, as will 'be understood byreference to Figure 1. Means f is provided 'forcontrollingthe'fric'tional engage in Figure 5.

of the rod in. dotted lines in Figure 1.

ment of the wax barswith the periphery of; the

drum 5, in order to accuratelycontrgl tlie transg fer or feeding of thewax from thewax-bar 9 onto the surface or floor being polished. i

To thus control the transfer or feeding of the wax onto the surface, aspring-actuated rod"l8 isshown slidably supported in a tubular guide l9mounted for axialadjus tment in a hub 2| fixed to a wall of the hood'B,as clearly illustrated in Figure 5. The hub 2| has its upper end portionsplit lqngitudinallyas indicated at 20 in Figure 1, and said split endis externally threaded, as shown at 22 ada'ptedto receive a loclc nut23, shown provided with an operating handle 24,

When the nut 23 is rotated in one direction, the upper endof the hub 2|is slightly contracted to secure the guide I9'in'adjusted position inthe hub 2|. When the nut 23 is released, the guide member I 9 may beaxially adjusted in the hub 2| to vary the pressureexe'rted on the waxto hold it in frictional contact with the periphery of the drum 5, aswill be understood.

A spring 25 isniounted in the upper end of the guide l9 andh'as itslower end engaging a collar 26 secured to the rod l8 by a suitable pinshown I he upper endof the spring 25 bears againstth'ebottom face of asleeve-like hub 21 shownintegrallyformed with aha'nd' grip or knob 28.The hub 21 is received in threaded engagement with the upper end of theguide member I9 and provides meanswhereby the tension of the'sprin' 125Qmay be varied to suit conditions'. f

Ahead 29 is secured to the lower end portion I2 above the holderI'I,iand engages the upper surface of the holder when the wax bar isheld in contact with the periphery of the polishingdrum Sunder tensionof the spring 25,,as shown in Figur 1. The lower end 'of therod I8 hasan enlargement 3| 7 adaptedto engage the bottom surface of the holder IIwhen the rod is pulled upwardly in the guide member I9, thereby to movethe wax bar out of contact with the periphery of the drum 5, asindicated Suitable spring clips 32 and 33gare provided at the ends ofthe holder II for preventinglo'ng'itudinal movement of the wax barintheholder, and to facilitate inserting the waxbar into the holder orremoving it therefrom. c l c The present invention, in its broadervaspect, resides, as hereinbefore stated, in the-novel manner of applyingthe .wax to the periphery of the polishing drum 5, whereby theapplicationof. the wax tov the surface-being polished may be ac curatelycontrolledunder all conditions, includ ing extreme temperature changes.This is made possible by molding orcompressing the wax into arcaneasolid'mass or bodmandsupportingsaid body in such a manner that itscontact with the periphery of. the polishing drum may be convenientlycontrolled at all times. V I

In addition to the use, ofmechanical; means for regulating theapplication of the wax to the surface to be treated, as'hereindisclosedusing a wax orother polishing materialin solid .form, permitsthe greatest latitude inthe use of polishing materials having the-propermelting-point,

.grain, and other characteristics whereby. a desired finish may beobtainedunder greatly'varying temperature conditions.

In'the drawings there is shown a pivoted. holder for supporting the waxbar which requires that the base or backing I of the waxbar 9 be shapedto fit into the holder ll asshown in-Figure '1.

Obviously, other forms of holders may be 'uti- ;lized and the wax barmay be otherwise 'f'ashioned without ,departing from thescope'of theinvention. For example, the wax bar may be made rectangular in crosssection wherebyit may be supported in a fixed guide mounted over thedrum 5 so that the wax bar may be held in feeding contact with theperiphery of the drum by gravity, or, if necessary, by the'applicationof variable pressure to the wax bar to control the transfer of the waxfrom the'wax bar to the surface being polished by the periphery of thedrum. a

By compressin'gthe wax into a solid mass or body, as shown in Figure 7,suitable anti-slip .niaterialmay be introduced into the waxibar,

V a liquid wax is impractical because of variations in the specificgravity of such materials and the liquid wax. The present method ofcompressing the wax into bar form and applying it to the floor to betreated by the periphery of the drum 5 also offers a wider latitude inthe use of synthetic materials having wax-like properties, whichheretofore have been impossible to use in an emulsifying process.

Another important advantage resulting from using wax in bar form, asherein disclosed, resides in the safety factor. Spirit wax isinflammable, whereas wax in bar form as herein shown is safe to use atall times. Wax in bar form is also relatively inert whereby it may bestored without deteriorating effects for long periods under a wide rangeof temperature changes.

As hereinbefore stated, in order to obtain a good waxing job it is ofutmost importance that the wax be applied to the surface of floor in athin uniform film, and then thoroughly buffing, burnishing, or rubbingsuch film of wax until the desired finish is obtained. When using wax inbar form, the application 'of the wax may be accurately controlled atall times resulting in the production of a better job with greatereconomy in the use of the wax. Wax in bar form is also void ofunpleasant odors, usually present in commercial waxes embodyingemulsifying agents or solvents in their manufacture.

The frictional or feeding contact of the wax bar with the periphery ofthe rapidly rotating drum 5 is of extreme importance, as the wax shouldbe applied to the floor in a thin uniform practically all operatingconditions. a

It will be apparent to those skilledin the art coating at all times.When operating in tern- -peratures which may vary from time to time, it

may be necessary to vary the pressure exerted on the wax bar to hold itin frictional or feeding :contact with the periphery of the drum. Forexample, when operating a polishing machine of this type in a warmclimate, the wax bar tends to soften more or less whereby greaterquantities thereof may be carried away by the-periphery of the drum 5,unless the pressure on the wax bar is decreased. Conversely, whenoperating in a relatively cooler temperature, the

wax bar may harden to the extent that it may be necessary to applyrelatively greater pressure on the wax bar in order to obtain thedesired .feeding contact between the wax bar and the periphery of thepolishing drum 5.

From the foregoing, it willthus be, seen that by the employment of thenovel method herein disclosed, the application of a polishingqwax to a.fioor "or other. surface may be accurately and conveniently controlledat all times, whereby the operation of waxing and polishing a surface isgreatly facilitated and with the assurance that a high grade polishingjob may be obtained under that I have accomplished at least theprincipal objects of my invention, and it will also be apparent to thoseskilled in the art that the embodiments herein I described may bevariously *changed and modified without departing from the spirit of theinvention, and that the invention is. capable of uses and has advantagesnot herein specifically described; hence it will be appreciated that theherein disclosed embodiments are illustrative only, and thatmy'inv'ention is not limited thereto.
